What version of the connector are you running?
In your Load field it looks as you have only ONE column field: it shows as:
LOAD [Field0_ ! SomeHeader1 ! SomeHeader2 ! SomeHeader3 !]
This means the columns needs to be separated by using the Field Delimiter "Add"-button, please see the manual how to do that.
Then it will look something like this:
Which you can change with AS:
Load [Field0_Material] AS 'name1',
[Field1_Descr] AS 'name2',
[Field2_Test] AS 'name3';
Is it possible to tick the "Auto Detect Column Width" box in that report? If so you would get the Fields automatically (Will not work on all types of Report)
